[infinispan-issues] [JBoss JIRA] Commented: (ISPN-312) Ability to group data entries

[Erik Salter (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603501#comment-12603501 ] 

Erik Salter commented on ISPN-312:
----------------------------------

How would you handle the following case?

Cache A uses a custom key class where the group is dynamically generated.  Cache B's key is an unmodifiable String that needs to be grouped with the dynamic value of a key from Cache A.  (Cache B's key can't be encapsulated in a custom key class since it needs to be queried from external entities that will not know the group context).

The only way I can see doing this is to add a group parameter to a put() or replace() method.

> This is a spin-off from http://lists.jboss.org/pipermail/infinispan-dev/2009-December/001968.html.
> The requested feature would allow distinct entries to be assigned to custom arbitrary groups. Later in time those groups could be flushed on demand without any knowledge of entry keys.
> This feature exists in other open source cache library, see: http://www.opensymphony.com/oscache/api/com/opensymphony/oscache/base/Cache.html
